Answer is (3) please explain how. . Select correct option for photosynthesis in C3 plants. (1) bifunctional nature of PEPCase (2) regeneration of each RuBP requires 6 Atp (3) first stable compound of Calvin cycle undergoes phosphorylation in dark reaction (4) optimum temperature 30-40 C
Dear Student,
Out of the given 4 options only option (3) is related to or satisfy condition for photosynthesis in C3 plants.
Explanation- In C3 plants PEPCase is absent as only RUBISCO is present so option (1) is not related to C3 plants hence, incorrect.
In C3 plants 3 ATPs are required to regenerate each RUBP so option (2) is incorrect.
Optimum temperature for C3 plants is around 18-25 oC while here given temperature in option(4) is for C4 plants. So, Option (4) is also incorrect.
First stable product of C3 cycle is 3-Phosphoglycerate which undergoes phosphorylation to give1,3-Biphosphoglycerate. So option (3) is correct.
Hope your doubt is cleared!
Thanks and Regards.
